By the most important media to deliver the contents on a remote instruction we commonly use audio and documents. A number of remote instruction system are trying to offer the video, but they did not acquire satisfiable results because of the limited network and width. Also, they use the general web browsers that have a lot of unspecific users access the contents. Also, they use the general web browsers that have a lot of unspecific users access the contents. Like this most systems that use the continuous media have not offer the satisfiable contents because of the network limitation. Moreover, because they use the web browser, they offer the contents having documents(web pages) only. In this paper, we propose a web-based remote instruction system on real-time using audio and documents which are the most important media for a information delivery. In addition to the system, we use a action synchronization mechanism between the web browsers. If the instructor uses web pages on his computer and explains the contents of them, the learners see the same web pages as the instructor's and listens to his voice.

The purpose of this study is to confirm the effect of recording online classes and real-time video classes on other behaviors, lecture satisfaction, and lecture flow in during the COVID-19 period. Data were collected and analysis using a structured questionnaire from May 20th to June 4th in 2021 for 550 nursing students in the D University. As a result of the study, it was found that there were more others behaviors in record online classes than in real-time online classes (t=-2.00, p=.046), lecture satisfaction(t=-1.54, p=.124) and lecture flow in real-time online classes it was higher in the record online classes (t=-.63, p=.529), but it was not statistically significant. However, the 2nd year students who participated in the two types of online classes showed statistically significantly higher lecture satisfaction (t=13.55, p=.000) and lecture flow(t=4.48, p=.004). And 4 th grade students of others behaviors was statistically significantly lower (t=4.68, p=.003). In the multiple regression analysis, the main factor affecting lecture flow was lecture satisfaction, and the explanatory power of the model was 55.1% in record online classes (F=128.49, p <.01), and in real-time classes 47.2%(F=77.24, p<.01). In the future, research should be conducted to confirm the difference between the two types of online classes of the same instructor and the difference in other things, lecture satisfaction, and class commitment that appear after applying learner-centered learning.

This study intends to analyze the learning effect of asynchronous online classes used in education fields around the world after the COVID-19 pandemic. To this end, we compared and analyzed the lecture evaluation and final exam questions of the HTML5 web programming course, which was conducted offline in 2019 and asynchronously online in 2020 due to COVID-19. As a result of the analysis, no significant difference was drawn between the two teaching methods in the lecture evaluation score and final exam score. However, contrary to concerns about the application of online classes to the entire curriculum, the lecture evaluation and final exam scores of the video-based online classes were high, suggesting the possibility that online classes could be more effective than offline classes if well organized and managed in the future.

This study divided video content of current representative YouTube channels on Chinese language education into internal and external elements for analysis. By examining these channels, this study found that they have various external and internal elements. In addition, YouTube classes also have certain distinct characteristics that are non-existent in traditional classroom or face-to-face classes, and show potential to serve as a new educational medium that can fill the gaps in existing classroom classes. However, a large number of these channels still have problems with their internal and external elements, which seem to require not only the effort and attention of the instructors creating the videos, but also considerable time and human and material resources.

The purpose of this study was to examine the effects on the academic achievement and learning satisfaction according to the presentation method of the multimedia materials for 'transportation technology' units of technology home economics subject. The subjects were assigned in third conditions; Text type explanation class, multimedia class and multimedia video class with narration. The data of six evaluation questions obtained from the survey of 93 high school girl were analyzed using SPSS program. The results of the study were as follows : First, in the learning satisfaction average level(M) of the students' overall responses to the questions, multimedia teaching learning class(experimental group 1) is the first(M=4.14), multimedia video class with narration(experimental group 2) is the second(M=3.16), and instructor-led class(control group) is the third (M=2.63). Therefore, the teaching learning multimedia class(experimental group 1) was most effective. Second, looking at the correlations between the students' responses to the questions, in an interesting class, the students have a retentive memory and comprehension, but a lower concentration can not a retentive memory. Third, multimedia teaching learning class(experimental group 1) has the best degree at the level of academic achievement, but instructor-led class(control group) and multimedia video class with narration(experimental group 2) have similar degree in the second place. To increase academic achievement, an instructor-led class is important to arouse interest and a multimedia video class with narration is required ways to improve level of concentration.

Purpose: The purposes of this study were to develop an infant sleep health education program using a video for SIDS prevention education and to measure the effects of the program. Methods: The infant sleep health education program consisted of presentations and motor images. The formation of educational material was directed by the systematic design of instruction. Participants in this study were 59 primiparous women from postpartum care centers. The instruments used in this study were criterion referenced test items for knowledge about infant sleep health and confidence inventory. Experimental group I was given the treatment of infant sleep health education program. Experimental group II was given the program using a video reinforcement after 2 weeks. On the other hand, control group was given no treatment. Results: There was a significant increase in knowledge and confidence in the performance of mother's roles of both experimental group I and experimental group II over the control group. No significant difference was founds for knowledge and confidence in the performance of mother's roles between experimental group I and II. Conclusion: The results indicate that this program is a very effective intervention for better sleep health in infants by helping the mothers increase confidence in their role performance.
